. This invention relates to the type of shinles which a're substantially square and laid iagonally'on the roof and provided with turned-under cornersito thicken tleir horizontal'loweredges and givetlieml a :Strong `and heavy appearance. Usually, they are composed of composition rooting such as felt saturated with asphalt and faced with crushed slate or similar mineral, to render them flexible.

Some of the objects of my invention are to Vsimplify the means forlocking the lower corner of' the shingle in place; to provide a strong concealed lock of this kind which will efectually withstand the lifting and loosening eect o fwind and rain storms and to ma-' terially reduce the cost of the saine.

further obj ect is to so construct the shingle and its locking device that the shingle can be 20 easily adjusted up or down on the roof to alineit with adjacentshingles inthe same row, and so that it is. free to expand and contract in response to changes of temperature, thuspreventing buckling ofthe shingle and l allowing it to lie smooth under all weather conditions.

' In the accompanying drawings: y Figure 1 is a fragmentary top plan viewl of a roof embodying the invent-ion. Figure 2 is 30 an enlarged fragmentary top plan View, part ly in section', on line 2 2, Fig. 3. Figure 3 is a vertical longitudinal section of the roof on line 3 -3, Fi 1. Figure 4 is a perspective view of one o the fasteners.

Similar characters Of reference indicate corresponding parts throughout/v the several .views lO'indicates the customary 4roof boards or slieathing and 11 the usual starting stri of.

40 roofing material laid along the margin o vthe i roof.

The shingles 12 are preferably constructed of roofing material of the character abo-ve described and laid diagonally in overlying courses as usual. `They 'are-cut square, as

shown, by suitable dies and the lower corner 13 of the shingle is folded or turned under its bod and provided centrally' with a substantial y vertical slot 14 which interlocks with the head or cross-bar 15 of a substantially T shaped fastener, by preference, of galvanized iron, the stem 16-of which passes through the slot and is driven through the underlying starting strip or shingle or both, into the roof board. The head orcrossebar of the fastener In laying and securing a shingle of this` Vimproveeleconstruction, assuming a course of suoli shingles to have been previously laid, one of the fasteners is driven into the roofboards with its shank located below and in line with the meeting side corners of two previously-laid shingles and with its crosshead arranged horizontal-ly, as shown in Fig. 1. A. shingle with its slotted corner folded is then intcrlocked with the cross-liead of the T-fastener by bringing the slot in line therewith, as shown by dot and dash lines in Fig. 2; then giving'the shingle an upward quarter turn or swing to the position shown by dottedlines in said figure, bri ging the slot at right angles to the cross-head, and finally .nailing the side corners of the shingles to the roof-boar'ds. To facilitate the turning v,or swinging movement of the shingle, the fend portions of the T-fastenei are beveled on their undersides, as shown'at 17, in Fig. 4.'

By this construct-ion, the shingle is securely .interlocked with the fastener and the latter is covered and concealed by the body of the shingle, producing a sightly roof exhibiting thick and heavy-appearing edges at the lower corners of the shingles.

Owing to the vertical arrangement of the locking-slots, the shingles, after being interthe flexible composition material, from'which such shingles are out, to expand or contract,

with the result that the shingles bulge and buckle, detracting from the sightliness of the roof. The slots of these improved shingles permit the necessary vertical play of the shingles to compensate for such weather changes, allowing them to remain flat under all conditions and preserving the attractiveness of the roof.

.ics

The lock, while affording a strong and reshin le with' the fastener,

liable fastening, is eirc'eedingly simpledn construction in that it involves no separate or additional parts and it can therefore be manufactured at a comparatively low cost.

The lock is 'ofsuch a character that when the shingle is once properly engaged with the fastener, it is impossible for it to become loosel or unlocked from it.v

In practice, the shank usually provided with av flange or shoulder 18 to limit .its penetrationinto the roof boards, the distance being predetermined so that the head 'of the fastener will not bind against the backl of the folded corner in interlocking the W ile the construction hereinbefore describedLhas been found very useful and desirable, I do notwish tol be limited to it as Y it may be modified .within the scope of thev appended claims.

`1 claim as my invention; f i

1. The combination of a roof,- a fastener of substantially T-form engaging the' roof,

of the fastener is.

yregles:

andv 'a iexihle shingle having ,a turned-.under lower corner provided with a slot interlock,` ing With said fastener, the body of the shingle overlying and concealing the fastener and the shingle ,slot being disposed atan langle to the cross-head of the fastener, requiring 'a partial turn of' theshingle relative to thefas'tener tointerlock its folded corner therewith. Y

2. The combination of a roof, a tener element engaging the roof, and aiiexible shingle having a turned-under lower corner provided -with a slot interlocking with saidv fastener when the shingle is in `a predetermined position and is moved inwardl relative to the roof, said slot provided y the lower cornerof the shinglecand fastener-bef ing adapted tobe brought into interlocking engagement upon a turning movement of the shingle -relative 'to the fastener, of the shingleoverlying and concealing the fastener and slot.
